get all the library inti's and functions to behave
multiple init calls should not cause undefined behavior
#5 Updated by David Schultz about 8 years ago
Multiple xbee init works if you call terminate at end of use before initing again. Otherwise it will get stuck in an infinite loop waiting for a response that won't come. We should probably make the call return an error if it waits for over a second with no response.
